Build stuck on "Deploying outputs" when I use more than a handful of cache tags

[timomeh]

Summary

Hey,

I optimized the caching of my Next.js site. Previously I only had very few cache tags (only 2 or 3 tags iirc) for all data, and I now have set more specific tags, where I have ~40 tags. This way I can run revalidateTag() for only exactly the data that has changed, so I don't slow down my whole site as soon as there's a single tiny change.

But now I cannot deploy my site anymore. It stalls at "Deploying outputs..." and then just does nothing until it times out after 20+ minutes.

I found an issue that is reporting exactly the same: vercel/next.js#59022

Specifically, it's not about the amount of tags on a single cache item. But overall the amount on tags. Even if I only have 1 tag per cache item.

I can also see that when I change the tags back so I only have a few (less than 5) unique tags overall, the deployment works again.

What can I do to fix this?

Thanks
